Abstract

The invention relates to a method for operating a strip casting machine ( 10 ), whereby molten metal ( 18 ) is poured between two rotatable casting rolls ( 11, 12 ). A gaseous film (G) is formed between the respective surfaces ( 11', 12' ) of the casting rolls and the strip skin (D 1 , D 2 , D 3 ) forming on the molten metal, the gas being introduced essentially into the inerting chamber ( 24 ) above the metal bath. During the casting, a controlled quantity of a gas consisting of argon, nitrogen and/or another gas is introduced into the inerting chamber ( 24 ) in such a way that the heat transfer from the strip skin to the casting rolls ( 11, 12 ) can be influenced by the thickness of the gaseous film (G) in such a way that the surfaces ( 11, 12 ') of the casting rolls can be provided with or without cavities ( 51 ). A smooth surface can thus also be obtained on the strip cast.

Die Erfindung bezieht sich auf ein Verfahren zum Betreiben einer Bandgiessmaschine, bei dem zwischen zwei drehbaren Giessrollen Metallschmelze eingegossen wird, wobei zwischen der jeweiligen Giessrollenoberflache und der bei dieser entstehenden Bandhaut der Metallschmelze ein Gasfilm gebildet wird, bei welchem das Gas in die oberhalb des Metallbades befindliche Inertisierungskammer eingebracht wird. Die Erfindung bezieht sich ferner auf einen Mantelring für die GiessroUe der Bandgiessmaschine.The invention relates to a method for operating a belt casting machine, in which metal melt is poured between two rotatable casting rolls, a gas film being formed between the respective casting roll surface and the band skin of the metal melt which forms in the process, in which the gas is in the one located above the metal bath Inerting chamber is introduced. The invention further relates to a jacket ring for the casting tube of the strip casting machine.
Bei einer GiessroUe gemäss der Druckschrift EP-A-0 309 247 sind auf ihrer Oberfläche gleichmässig verteilte Vertiefungen eingearbeitet, die jeweils beabstandet zueinander angeordnet sind. Mit diesen Vertiefungen wird beim Abgiessen erreicht, dass sich in diesen Gasblasen bilden, mit welcher primär Risse in der Bandhaut der verfestigten Metallschmel-In the case of a casting tube according to the document EP-A-0 309 247, evenly distributed depressions are incorporated on its surface, which are each arranged at a distance from one another. With these depressions it is achieved during casting that gas bubbles form in these, with which cracks primarily form in the band skin of the solidified metal melt.
BESTATIGUNGSKOPIE ze verhindert und ferner eine ausreichende Wärmeleitfähigkeit bezweckt wird. Mit diesen Vertiefungen entsteht jedoch an der Oberfläche des gegossenen Metallbandes eine entsprechende Rauheit. Ausserdem sind diese Giessrollen jeweils relativ schnell wieder nachzuarbeiten, da sich die Vertiefungen, die bis zu 100 Mikrometern aufweisen können, durch die Abnützung der Rollenoberfläche reduzieren. Diese Vertiefungen oder Texturen, in denen sich relativ schnell Schmutz ansammelt, sind zudem häufig zu reinigen.BESTATIGUNGSKOPIE ze is prevented and a sufficient thermal conductivity is also intended. With these depressions, however, a corresponding roughness arises on the surface of the cast metal strip. In addition, each of these casters can be reworked relatively quickly, since the indentations, which can be up to 100 micrometers in size, are reduced by the wear on the surface of the rollers. These depressions or textures, in which dirt accumulates relatively quickly, are also often to be cleaned.
Aufgabe der vorliegenden Erfindung besteht demgegenüber darin, ein Verfahren nach der eingangs erwähnten Gattung zu schaffen, mittels welchem die Oberflächenrauheit des zu giessenden Metalibandes bestimmt werden kann, auch bei Verwendung von Giessrollen mit über ihre Oberfläche verteilten Vertiefungen.In contrast, the object of the present invention is to provide a method according to the type mentioned at the outset, by means of which the surface roughness of the metal strip to be cast can be determined, even when using casting rolls with depressions distributed over their surface.
Die Aufgabe ist erfindungsgemäss dadurch gelöst, dass während des Giessens eine gesteuerte Menge eines Gases aus Argon, Stickstoff und/oder eines anderen Gases in die Inertisierungskammer zugeführt wird, so dass der Wärmeübergang von der Bandhaut auf die GiessroUe durch die entstehende Filmdicke des Gasfilmes so beeinflusst werden kann, dass die Giessrollenoberflache mit oder ohne Vertiefungen vorgesehen und eine glatte Oberfläche des zu giessenden Bandes erzielt werden kann.The object is achieved according to the invention in that a controlled amount of a gas of argon, nitrogen and / or another gas is fed into the inerting chamber during the casting, so that the heat transfer from the band skin to the casting tube is influenced by the resulting film thickness of the gas film can be that the casting roll surface can be provided with or without depressions and a smooth surface of the strip to be cast can be achieved.
Bei einer sehr vorteilhaften Ausführung wird als Gas ein definiertes Gemisch von Argon und Stickstoff verwendet, mittels dem die Rauheit der Oberfläche des zu giessenden Bandes wunschgemäss eingestellt werden kann.In a very advantageous embodiment, a defined mixture of argon and nitrogen is used as the gas, by means of which the roughness of the surface of the strip to be cast can be adjusted as desired.
Im Bereich der Vertiefungen wird durch das grössere Gaspolster partiell weniger Wärme abgeführt, was eine wabenförmige Struktur des entste-In the area of the depressions, less heat is partially dissipated through the larger gas cushion, which results in a honeycomb structure of the resulting
BESTATIGUNGSKOPIE henden Bandes und damit eine grössere Dehnung im vertieften Bereich der Rollenoberfläche ergibt, womit mögliche Schrumpfrisse vermieden werden können.BESTATIGUNGSKOPIE tape and thus greater elongation in the recessed area of the roll surface, with which possible shrinkage cracks can be avoided.
Mit diesem erfindungsgemässen Verfahren kann die Oberflächenrauheit des zu giessenden Metallbandes durch die Verwendung eines definierten Gasgemisches minimal gehalten werden.With this method according to the invention, the surface roughness of the metal strip to be cast can be kept to a minimum by using a defined gas mixture.

Es sind hierbei zwei zueinander beabstandete Giessrollen 1 1 , 12 mit jeweils einer horizontalen Drehachse vorgesehen, wobei durch den gebildeten Spalt 19 zwischen den Giessrollen 1 1 , 12 das erzeugte Metallband weggeführt wird. Durch eine abgedichtete Öffnung 14' beim oberen Abschlusselement 14 ragt ein Giessrohr 25, welches am Ausguss eines nicht näher gezeigten Behälters gehalten ist. Oberhalb des zwischen den Rollen 1 1 , 12 entstehenden Metallbades ist eine geschlossene Inertisierungskammer 24 gebildet, welche über je eine Anschlussleitung 29 mit einem Inertisierurigsgas auffüllbar ist. Vorteilhaft wird über1 shows two casting rolls 11, 12, a side seal 16 and an upper end element 14 with sealing strips 13, 17, of a band casting machine 10 used in particular for the production of steel strips. There are two casting rolls 11, 12 spaced apart from one another, each with a horizontal one Axis of rotation provided, the metal strip produced being guided away through the gap 19 formed between the casting rolls 11, 12. A pouring tube 25, which is held on the spout of a container (not shown in any more detail), projects through a sealed opening 14 'in the upper end element 14. A closed inerting chamber 24 is formed above the metal bath formed between the rollers 11, 12 and can be filled with an inert gas via a connecting line 29. Will be beneficial
BESTATIGUNGSKOPIE eine weitere Anschlussleitung 31 ein zusätzliches Schutzgas 32 von der Kammer 24 weg auf die jeweilige Rollenoberfläche 1 1 ', 12' geblasen, um letztere vor jeglicher Sauerstoffablagerung freizuhalten.BESTATIGUNGSKOPIE a further connection line 31 blows an additional protective gas 32 away from the chamber 24 onto the respective roller surface 11 ', 12' in order to keep the latter free from any oxygen deposition.
Gemäss Fig.2 wird zwischen der jeweiligen Giessrollenoberflache 1 1 ' und der bei dieser entstehenden Bandhaut D der Metallschmelze 18 ein Gasfilm gebildet, bei welchem das Gas im wesentlichen in die oberhalb des Metallbades befindliche Inertisierungskammer 24 eingebracht wird.According to FIG. 2, a gas film is formed between the respective casting roller surface 11 ′ and the band skin D of the molten metal 18 that is formed, in which the gas is essentially introduced into the inerting chamber 24 located above the metal bath.
Mit dem erfindungsgemässen Verfahren wird während des Giessens durch die Anschlussleitung 29 eine gesteuerte Menge eines Gases G3 aus Argon, Stickstoff und/oder einem Drittgas in die Inertisierungskammer 24 zugeführt, so dass der Wärmeübergang von der Bandhaut D3 auf die GiessroUe 1 1 , 12 durch die entstehende Filmdicke des Gasfilmes G3 so beeinflusst werden kann, dass die Giessrollenoberflache 11 ', 12' mit (oder ohne) Vertiefungen vorgesehen und eine glatte Oberfläche des zu giessenden Bandes erzielt werden kann.With the method according to the invention, a controlled amount of a gas G3 of argon, nitrogen and / or a third gas is fed into the inerting chamber 24 during the casting through the connecting line 29, so that the heat transfer from the band skin D3 to the casting tube 11, 12 through the The resulting film thickness of the gas film G3 can be influenced in such a way that the casting roller surface 11 ', 12' can be provided with (or without) depressions and a smooth surface of the strip to be cast can be achieved.
Bei dem Mantelring für die jeweilige GiessroUe 1 1 , 12 ist das Basismaterial A mit einem Auftrag einer zusätzlichen Materialschicht C versehen, welche Keramik- oder Cermetpartikel enthält. Diese auf dem Basismaterial A aufgetragene Keramikschicht C weist über die gesamte Oberfläche verteilte Vertiefungen 51 im Mikrometerbereich auf, die beispielsweise durch eine Sandstrahl- oder Laser-Aufrauhung erzeugbar sind. Durch diese Vertiefungen entsteht ein angedeuteter Wärmeübergang φ, der sich durch eine sägezahnförmige Kurve manifestiert.In the case of the casing ring for the respective casting tube 11, 12, the base material A is provided with an application of an additional material layer C which contains ceramic or cermet particles. This ceramic layer C applied to the base material A has depressions 51 in the micrometer range distributed over the entire surface, which can be produced, for example, by sandblasting or laser roughening. These recesses result in an indicated heat transfer φ, which is manifested by a sawtooth curve.
In Fig.2 sind drei Varianten von unterschiedlich verwendeten Gasen G1 , G2, G3 veranschaulicht, mittels welchen das grundsätzliche Verhalten durch die verschiedenen Gase aufgezeigt ist: Bei dem Gas G1 handelt es sich mehrheitlich um Argon, welches nicht in das abzugiessende Metall diffundiert und dementsprechend bei der jeweiligen Vertiefung durch die Erhitzung eine Ausdehnung erfährt, so dass sich in der Bandhaut D1 eine Einbuchtung selbstverständlich im Mikrometerbereich bildet, wobei die Haut hierbei dünner als im Bereich neben der Vertiefung ist.2 shows three variants of gases G1, G2, G3 used differently, by means of which the basic behavior by the different gases is shown: The majority of the gas G1 is argon, which does not diffuse into the metal to be poured off and accordingly expands in the respective depression due to the heating, so that an indentation in the band skin D1 is of course formed in the micrometer range, the skin being thinner than in the area next to the depression.
Bei dem Gas G2 wird mehrheitlich Stickstoff verwendet, welches teilweise in das abzugiessende Metall 18 diffundiert. Es entsteht somit eher eine Ausbauchung der Bandhaut D2.The gas G2 mostly uses nitrogen, which partially diffuses into the metal 18 to be poured off. This results in a bulging of the ligament D2.
Bei dem Gas G3 ist ein Gemisch von Argon und Stickstoff verwendet. Mit diesem Gemisch wird im Sinne der Erfindung der Idealzustand erreicht, nämlich dass die Bandhaut D3 weder ein- noch ausgebuchtet wird und somit eine glatte Oberfläche bei dem herzustellenden Band entsteht. Durch die dosiert gesteuerte Menge des definierten Gemisches von Argon und Stickstoff kann ohne grossen Aufwand diese glatte Oberfläche bei dem Metallband erzielt werden.A mixture of argon and nitrogen is used for the gas G3. In the sense of the invention, this mixture achieves the ideal state, namely that the band skin D3 is neither indented nor bulged out, and thus a smooth surface is produced in the band to be produced. Due to the controlled amount of the defined mixture of argon and nitrogen, this smooth surface can be achieved with the metal strip without great effort.
Das Basismaterial A ist hierbei aus reinem Kupfer, aus einer Kupferlegierung mit den Hauptbestandteilen Cu, Ag oder Cu, Cr, Zr oder Cu, Ni, Be (Beryllium) oder aus Stahl, insbesondere einem legierten Stahl, hergestellt. Es zeichnet sich durch die gute Wärmeleitfähigkeit aus, durch die gewährleistet ist, dass das durch einen Kühlkanal fliessende Wasser bei dem Mantelring der GiessroUe möglichst viel Wärmeenergie abführt.The base material A is made from pure copper, from a copper alloy with the main components Cu, Ag or Cu, Cr, Zr or Cu, Ni, Be (beryllium) or from steel, in particular an alloy steel. It is characterized by the good thermal conductivity, which ensures that the water flowing through a cooling channel in the jacket ring of the GiessroUe dissipates as much thermal energy as possible.
Fig.3 zeigt vergrössert einen Ausschnitt einer zylindrischen Manteloberfläche, die glatt ausgebildet ist, die vorzugsweise mit einer Oberflächenrauheit von weniger als 6, vorzugsweise weniger als 1 Mikrometer, vorgesehen ist, und daher durch Schleifen oder Drehen feinbearbeitet ist. Es ist ausserdem eine auf das Basismaterial A aufgetragene Material-3 shows an enlarged detail of a cylindrical surface which is smooth, which is preferably provided with a surface roughness of less than 6, preferably less than 1 micrometer, and is therefore finished by grinding or turning. It is also a material applied to the base material A
BESTATIGUNGSKOPIE schicht B vorgesehen, die vorzugsweise aus Nickel, Stahl und/oder Chrom besteht. Die Materialschicht B und die Materialschicht C sind durch ein thermisches Spritzverfahren, wie zum Beispiel durch Plasmaspritzen, Flammspritzen, durch HIP cladding oder durch ein andere Beschichtungsmethode, zum Beispiel Elektrolyse, aufgetragen.BESTATIGUNGSKOPIE Layer B is provided, which preferably consists of nickel, steel and / or chrome. The material layer B and the material layer C are applied by a thermal spraying process, for example by plasma spraying, flame spraying, by HIP cladding or by another coating method, for example electrolysis.
Zum Beispiel kann das Basismaterial A aus Stahl oder einer Stahllegierung, indessen die Materialschicht B als legierter Stahl, die durch ein Schweissauftragen erzeugt ist, und die Materialschicht C als ein dünner Keramikauftrag von ca. 0.2 bis 0.4 Millimetern bestehen.For example, the base material A can consist of steel or a steel alloy, however, the material layer B as alloy steel, which is produced by welding, and the material layer C as a thin ceramic application of approximately 0.2 to 0.4 millimeters.
Die aus zwei verschiedenen Keramikmaterialien C1 , C2 bestehende Materialschicht C auf der Materialschicht B ist derart aufgetragen, dass sich das eine Keramikmaterial C2 über die gesamte Mantelfläche erstreckt und das andere Keramikmaterial C1 in annähernd gleichmässigen Abständen als Partikel im ersten Material C2 eingebettet ist. Damit wird ein ausreichender Schutz der Schicht B und des Basismaterials A erreicht und gleichzeitig eine genügende Wärmeleitfähigkeit erzeugt. Die Abnützung der Materialschicht C ist durch die Wahl der Materialien C1 und C2 sehr gering. Für die Keramik- bzw. Cermetschichten C1 , C2 sind insbesondere Al203, SiAI202, PSZr02, Si3N4 SiAlON, SiAlYON und/oder SiC verwendbar.The material layer C consisting of two different ceramic materials C1, C2 is applied on the material layer B in such a way that the one ceramic material C2 extends over the entire outer surface and the other ceramic material C1 is embedded as particles in the first material C2 at approximately uniform intervals. Adequate protection of the layer B and the base material A is thus achieved and at the same time sufficient thermal conductivity is generated. The wear of material layer C is very low due to the choice of materials C1 and C2. For the ceramic or cermet layers C1, C2 in particular Al 2 0 3, SiAl 2 0 2, PSZr0 2, Si 3 N 4 SiAION, SiAlYON and / or SiC are usable.
Erfindungsgemäss ist wiederum während des Giessens eine dosiert gesteuerte Menge eines Gases aus Argon, Stickstoff und/oder einem Drittgas in die Inertisierungskammer zugeführt, so dass der Wärmeübergang von der Bandhaut auf die GiessroUe durch die entstehende Filmdicke des Gasfilmes G so beeinflusst werden kann, dass die Bandhaut D1 eine glatte Oberfläche bildet.

The ceramic material C1 embedded in particles at approximately uniform intervals in the first material C2 is
BESTATIGUNGSKOPIE wirkt einen unterschiedlichen Wärmedurchgang, der im Bereich der Partikel C1 geringer ist als bei C2, was dazu führt, dass die Bandhaut D2 bei C1 reduziert ist. Mit dem vorzugsweise aus einem definierten Gemisch von Gasen zusammengesetzten Gasfilm G wird eine ausgleichende Wirkung erzielt, um die gewünschte glatte Oberfläche des Bandes erzielen zu können.BESTATIGUNGSKOPIE acts a different heat transfer, which is lower in the area of the particles C1 than in C2, which means that the band skin D2 is reduced in C1. A balancing effect is achieved with the gas film G, which is preferably composed of a defined mixture of gases, in order to be able to achieve the desired smooth surface of the strip.
Die Giessrollenoberflache 1 1 ', 12' kann auch eine Oberfiächenrauheit von 6 bis 10 Mikrometern aufweisen und dabei nur mit der aufgebrachten Materialschicht C ohne Nachbearbeitung versehen sein.The cast roller surface 1 1 ', 12' can also have a surface roughness of 6 to 10 micrometers and only be provided with the applied material layer C without post-processing.
Der Mantelring der GiessroUe 1 1 , 12 wird nach dem Gebrauch, wenn seine Oberflächenschicht um mindestens 0.1 bis 0.4 Millimetern abgenützt ist, für einen weiteren Gebrauch vorteilhaft wieder auf den ursprünglichen Durchmesser beschichtet. Dies geschieht dadurch, dass nach der entsprechenden Abnützung eine aus Keramikpartikeln oder Cermetschicht bestehende Materialschicht C aufgetragen wird.After use, when the surface layer of the GiessroUe 1 1, 12 is worn, by at least 0.1 to 0.4 millimeters, the jacket ring is advantageously coated on the original diameter for further use. This is done by applying a material layer C consisting of ceramic particles or cermet layer after the corresponding wear.
Die Erfindung ist mit den oben erläuterten Ausführungsbeispielen ausreichend dargetan. Sie Hesse sich jedoch noch in anderen Varianten darstellen. So könnten zum Beispiel die Materialschicht B und die aus den Keramikpartikeln bestehende Materialschicht C gleichzeitig auf das Basismaterial aufgetragen werden. The invention is sufficiently demonstrated with the exemplary embodiments explained above. However, they are presented in other variants. For example, the material layer B and the material layer C consisting of the ceramic particles could be applied simultaneously to the base material.
